Controlling the Transmission Dynamics of COVID-19	2020-03-31		.txt	text/plain	2868	170	52	In this article, we consider an optimal control COVID-19 transmission model and assess the impact of some control measures that can lead to the reduction of exposed and infectious individuals in the population. We investigate three control strategies for this deadly infectious disease using personal protection, treatment with early diagnosis, treatment with delay diagnosis and spraying of virus in the environment as time-dependent control functions in our dynamical model to curb the disease spread. In this section, we formulate an optimal control model for COVID-19 to derive four control measures with minimal implementation cost to eradicate the disease after a defined period of time. In this subsection, solution trajectories for the number of exposed, infectious with delay diagnosis and virus in the environment for all the three control strategies are numerically compared with that of the non-optimal control model.	./cache/cord-190242-sb0mjhzm.txt	./txt/cord-190242-sb0mjhzm.txt
